Arruruerie, Aaroniero

アーロニーロ・アルルエリ

Espada #09, the final member of the original Espada and the sole Gilian-class Arrancar, possesses the ability to devour and replicate the powers of other Hollows. Among the 33,650-plus Hollows he consumed was Metastacia, the entity that had taken control of Kaien Shiba's body, the former assistant captain of the 13th Squad in the Seireitei. He assumed this form (Kaien Shiba) in an attempt to manipulate Rukia Kuchiki into killing her friends as atonement for Kaien's death. However, Rukia could not accept this premise; recognizing that Aaroniero was not truly Kaien, she attacked. After revealing his true form (Glotonería), he stabbed Rukia with Kaien's zanpakutō, Nejibana. Upon being impaled, she felt guilt for failing to save Kaien, but then recalled that she carries Kaien's heart. Rukia ultimately kills him by impaling one of his two heads and shattering the "stasis tank" in which his heads were kept.
